Description
Technical field
The utility model belongs to lubrication technical field, relates to a kind of lubricating fitting, relates in particular to a kind of lubricating fitting that has the air chamber pressure fuel tank.
Background technique
At present, grease centralized lubrication technology is quite extensive in the application of China, and it can implement timing, quantitative automatic oiling to each lubricating point in the machinery running state.This class device has overcome the shortcoming of manual oiling.For example, have the KFP type gear pump arrangement of the serial plunger pump-unit of the LINCOLN that sells, VOGEL series plunger pump-unit, Ningbo three waves etc. on the market, these lubricant pump devices use the tubular fuel tank mostly, and the fuel tank upper chamber portion all directly communicates with atmosphere, and air pressure equals barometric pressure.These lubricant pump devices have adopted spring--the structure of various supplementary lubrication pump filler opening oil-feeds such as piston structure, vacuum chuck, rabble arm, scraper plate respectively in fuel tank, use the filling demand of low stickiness grease lubrication when having satisfied all kinds of mechanical friction pairs substantially and moving at normal temperatures.But for requiring high viscosity heavy oil fat and low temperature environment or the hypobaric machinery of normal operation down in the winter time, these present lubricant pump device pumping capacities all are difficult to satisfy.Reason is, the structure role of above-mentioned various supplementary lubrication pump filler opening oil-feed is limited, the limited pull of vacuum that lubricant pump self produces when mainly still relying on operation sucks lubricating grease, be difficult to suck high viscosity heavy oil fat, cause the filler opening of lubricant pump effectively to suck the capacity grease even find time.At present for requiring to use high viscosity heavy oil fat and low temperature environment or hypobaric most machinery of operation down in the winter time, armrest moves grease-gun lubrication, reduce the grease that friction lubricating is required to use low stickiness, this will reduce the usability of machine, the influence operation, and machine is damaged in early days.
The model utility content
The purpose of this utility model provides a kind of lubricating fitting that has the air chamber pressure fuel tank, improve the lubricant pump pump-conveying property, so that the pumping lubricating grease of high viscosity grade more satisfies all kinds of friction lubricating demands, adapt to harsh low temperature and hypobaric, to improve lubrication effect.
The utility model adopts following technical proposals to achieve the above object: a kind of lubricating fitting that has the air chamber pressure fuel tank, comprise the lubricant pump housing, power assembly, lubricant pump, the tubular fuel tank, piston, seal ring, power assembly and be installed on the lubricant pump housing by the lubricant pump of its driving, the tubular fuel tank is fixedlyed connected with the lubricant pump housing, piston is separated into the tubular fuel tank by seal ring fuel tank epicoele A and fuel tank cavity of resorption B two-part of mutual sealing, the filler opening C of lubricant pump communicates with the fuel tank cavity of resorption B that is used to store grease, described fuel tank epicoele A is a sealed air chamber, and fuel tank epicoele A is connected to the valve cock that stretches out its top.
Described fuel tank epicoele A is connected to the air pressure monitor unit that stretches out its top.
Described fuel tank epicoele A is connected to the safety valve that stretches out its top.
The utility model can reach following good effect after adopting said structure: becoming lubricant pump filler opening suction grease is main oil-feed mode into main oil-feed mode for the powerful grease that is pressed into, guarantee that the oil-feed of lubricant pump filler opening is abundant, have the pumping grease ability more much higher than existing product, even under certain low temperature and lowpressure, also can pumping high viscosity grease, enlarged Applicable scope simultaneously.
Description of drawings
Accompanying drawing is lubricating fitting embodiment 1 structural representation that the utility model has the air chamber pressure fuel tank.
Embodiment
Below by accompanying drawing the utility model is described further.In having lubricating fitting embodiment 1 structural representation of air chamber pressure fuel tank, lubricant pump housing 1, tubular fuel tank 7 and loam cake 9 are fixed by four double-screw bolts 4, wherein lubricant pump housing 1 top and mating face, tubular fuel tank 7 lower end seal mutually, loam cake 9 and mating face, tubular fuel tank 7 upper end compress sealing by seal ring 8, power assembly 2 and be installed on the lubricant pump housing 1 by the lubricant pump 3 of its driving, tubular fuel tank 7 is separated into the fuel tank epicoele A and the fuel tank cavity of resorption B of mutual sealing by piston 6 and seal ring 5, piston 6 and seal ring 5 can move along tubular fuel tank 7 inwalls under pressure, fuel tank cavity of resorption B stores the filler opening C of grease and conducting lubricant pump 3, fuel tank epicoele A forms sealed air chamber, fuel tank epicoele A top is connected to the joint 11 of its inner chamber of conducting, joint 11 is fixed on loam cake 9 tops, air pressure monitor unit 10, valve cock 13 and safety valve 12 are communicated with fuel tank epicoele A by joint 11 respectively, air pressure monitor unit 10 can be a barometer, it also can be baroceptor, in order to monitor the air pressure of fuel tank epicoele A, valve cock 13 is used for inflation and venting, valve cock 13 has non-return valve function, safety valve 12 limits the highpressure of fuel tank epicoele A inner chambers, the limit value of safety valve 12 is adjustable, power assembly 2 is in order to provide power and to drive the lubricant pump operation, can constitute by motor and driver part, also can constitute by air pump and driver part, above-mentioned tubular fuel tank 7 can be top bind lower openings fall " U " shape structure, can simplify loam cake 9 and the seal ring 8 among the embodiment 1 this moment, sealing configuration also can be made in the bottom of above-mentioned tubular fuel tank 7, and this moment, fuel tank cavity of resorption B communicated with the filler opening C of lubricant pump 3 by pipeline.
Its working principle is as follows: pass through valve cock 13 after fuel tank epicoele A inflation with external air source, pressurized gas clamping piston 6 in the fuel tank epicoele A, form pressure by piston 6 and then to the grease in the fuel tank cavity of resorption B, when lubricant pump 3 operations, the filler opening C that grease in the fuel tank cavity of resorption B will be pressed towards lubricant pump 3 with elevated pressures so just can guarantee that filler opening C oil-feed is abundant; Further, air pressure monitor unit 10 and safety valve 12 are set, can be according to the pressure information of air pressure monitor unit 10 demonstrations, when fuel tank epicoele A internal air pressure hangs down, in time inflate to fuel tank epicoele A by valve cock 13 with external air source, safety valve 12 is in order to limit the inflation pressure of fuel tank epicoele A.When fuel tank cavity of resorption B grease is used up need filling grease, can bleed off gas in the fuel tank epicoele A by valve cock 13, like this, resistance will be much smaller during the filling grease.This lubricating fitting can with supporting uses such as air pump, gas tank, can inflate by hand, also can with automatic controller and the supporting automatic inflation of electric air pump.
